INKING IYIEG'I-EANI FDR- PRIFTING PRESSES.

Application filed Februaryfl, 1922. Serial No. 536,410..

To all iol z'omfz't may concern:

Be it known that 1, Isaac Q'S IHER, a

citizen of the United States, residing-at l6 Grandview Ave, North Plainlield, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in lnking Mechanism for Printing Presses; and I hereby declare that the following is a full, clear, and exact de= sc iption thereof, reference being 'had'to the ly disseminate and uniformly distribute the inkon the distributing-surface, whetherit' be cylindric or flat, and to do away withthe ordinary 'vibra-tors'or distributorrolls'; and

the present invention consists broadly in dis tributing ink upon such surface by means of ink distributing aneinbers, preferably disks or rubbing devices which operate upon the distributing surface" to distribute the ink thereon; said distributing members as I shall hereinafter term thempreferably being; arranged to rotate on axes approximately perpendicular to the distributing surface. 1

In the-accompanying drawings-I have illustrated one practical embodiment of the invention which-I will descri'bein detail to enable others skilled in the artto unden' stand and use thes'ame but 'the'-1nvent1on- 1S DOlf-IGSlZI'lClIGCl to "the particular embody reof illustrated in the drawings and ier [O the claims for}su;'nmaries of the -ntials of the invention and novel feain said drawings Figil is adiagram'matical sectional elevation of an-inking appa ratusembodyingthe inventions Fig. 2 is a diagrammatical-detail View on the line 22, 1, showingthe arrangementof i es of construction and novel coinbina ions'of parts for which I desire )IOt6Ct1OI1'.-'

to the distributi'ngsurface upon which the ink is to be distributed as a drum, but this surface may be an ordinary inking drun'z, such as is commonly used in printing presses, or any other form of surface, curved or flat, upon which the ink is to be d'stributed. I will also refer to the ink d stribto include any kind of rubbing devices which operate to distribute the ink distributing surface, and preferably rotate on axes perpendicular to the surfacev on which the ink is to be distributed Thedrum 1 may be of any desired type, and ink might be supplied to the surface of this drum by any preferred means. In the example shown the drum may-be supplied,- with ink from an ordinary fountain F bymeans of a ductor D in the well known man ner. The 111k may be transferred from the surface of the drum 1 to the printing sur-- face by any suitable means, and in accorcance with the construction of the press or mac-hine to which theinvention is applied;

In the example-shown form rollersR- transferlnk from the surface of the drum 1 to a platecyllnder P;

Arranged beside drum '1 and cooperating with the surface thereof is a plurality of series of ink distributing disks 2 which extend longitudinally of the drum. A The disks in one series alternatewith the disks in the adjacent series. Preferably these disks are set at a tangent to the drum, and are preferably. mounted to-rotate on axes approximate ly perpendicularto the distributing surface and to the axis of the drum.

' As shown each disk 2 may comprise an annular distributing portion 2 secured to the fac 'of a circular head 2* on the spindle 2; portion 2 being preferably clamped against the head 2 by means of a bevel nut 2 engaging'a threaded part 2 of the spindle which projects beyond the head as shown. This permits the portion 2'to 'be readily renewed when it becomes worn. Portion 2* should be of a suitable material adapted to distribute the inkon the surface of the drum 1 where it contacts therewith,

and to have slightlyyielding or rubbing contact with-the surface of the drum.

or tangent to the drum that-only part of the portion 2 of the disk contacts with the sur face of the drum 1, as shown in Fig. 2.

As shown in Fig. 2,

; uting" members as disks, meaning thereby on such The distributing disks are-set at such an "angle only so much of the face of each portion 2* (of the upper series of disks) as lies between the points eb contacts with the periphery of the drum 1;

while so much of the face of the portions 2 of the lower series of disks, (which alternate with the disks in the upper series) as lie between the points a-b contact with the periphery of the disk; and, as indicated in Fig. 2, the portions of the drum not contacted by the upper series of disks 2 is contacted by the lower series of disks, so that the entire surface of the drum will be actually operated upon by the disks in both series. I have only shown tvo series of disks but, if desired, three or more series could be used to enhance the distribution.

In the example shown the spindles 2 are journaled in suitable bearing brackets 3, 3, which may be fastened to any suitable sup- 39 port on or in the main frame of the pre s; the. particular means of support being inn material. Upon each spindle 2 intermediate the supports is a worm gear .4 which meshes with a worm gear roll 5 extending longitudinally of the series of distributing disks, intermediate the upper and lower sets of worm gears 1, as indicated in Figs. 1 and 4t, and adapted to simultaneously ope ate all of the gears.

The roll gear 5 may be. driven by any suitable means, not shown, so as to impart any desired speed of rotation to the distributing disks 2. The inking drum 1 may also be driven by any desired means, not shown, so as to cause it to rotate; such driving means form no part of the present invention, and will be readily supplied by a mecnanic, and therefore are not illustrated herein.

The invention is not restricted to a worm gear drive for the disks 2, nor to the particular arrangement of supports for said disks as shown in the drawings.

The disks 2 may be yieldingly pressed against the periphery of roll 1 in any suitable manner. In the example shown the rear ends of spindles 2 are reduced in diameter (see Fig. 1) and a helical spring 6 is placed in the bearing 3 and interposed between a bushing 7 screwed into the outer end of 3, and a shoulder f2 on the spindle 2. By adjusting this bushing the tension of the spring 6 can be regulated so that it will act to yieldingly hold the disk 2 against the L5 drum 1 with any desired degree of pressure.

0 pemtz'on.

If the drum 1 is rotated in the direction of the arrow as shown in Fig. 1, the ink supplied thereto from the fountain I will be distributed on the surface of the drum by the action of the disks 2, which rotate approximately at right angles to the axis of the drum and distribute the ink not only circumferentially but longitudinally of the drum, and by reason of the plurality of sc ries of these distributing disks the ink is thoroughly disseminated over the entire sur-' face of the drum.

I have shown but two series of distributing disks, but if a finer or more uniform distribution of ink is desired additional series of distributing disks can be employed, as will be obvious. Also the disks in each series may be set closer together so as to get more distributing disks in each series. The number of distributing disks employed will depend upon the size of such disks; the distance apart of such disks in each series; and the number of series of disks.
